Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0012] The protocol is divided into three stages, the first stage completes the exchange of local energy information ( figure 1 , figure 2 ). Each node diffuses its own residual energy information group to its adjacent area with period T. Each node shall hold a sequence number seq. Each remaining energy information packet carries the following information: source node id value, seq value, remaining energy value of the node, TTL value. The initial value of Seq is 0, and the seq value is increased by 1 every time this type of group is diffused. The TTL value indicates the range (hop count) over which the packet can be flooded. In this way, an energy information packet can be uniquely identified through the seq value and the id value, avoiding repeated forwarding by intermediate nodes. Moreover, seq can identify the freshness of the energy information pack...

Abstract

The invention belongs to the field of energy-saving broadcast routing of the wireless sensor network, and particularly relates to an efficient energy flooding method oriented to the wireless sensor network. According to the method, in the wireless sensor network, the sequence information of node energy within the local range is utilized for achieving a broadcast tree structure method, so that the node energy is utilized regularly, and the service life of the wireless sensor network is prolonged.

Description

technical field [0001] The invention belongs to the field of wireless sensor network energy-saving broadcast routing. It specifically relates to a method of exchanging energy information of nodes in a local area in a wireless sensor network to obtain energy order information of nodes in a local area, and apply it to the broadcast tree structure to achieve a balanced use of network node energy and extend the wireless sensor network. The goal of web life. Background technique [0002] The wireless sensor network is composed of sensor nodes and information collection (sink) nodes. The sensor nodes are responsible for data collection and transmission. The sink node is responsible for summarizing the data sent by the sensor nodes in the network. It is also the control node of the entire network. Nodes are managed. [0003] Since the nodes in the wireless sensor network are deployed, it is difficult to recover them. Therefore, it is difficult to replace or recharge the batterie...
